How to Estimate Paint Quantity?
Calculating the exact amount of paint is crucial for project budgeting. Buying too little causes color mismatch issues later, while buying too much is a waste of money.
The Formula:
1. Calculate Total Area: (Wall Length × Height) - (Windows + Doors)
2. Apply Coverage Rate: Divide the area by the paint's coverage rate.
- Standard Paint Coverage: 10 m² per Liter (approx. 400 sq ft per gallon).
- Rough surfaces require 20% more paint.
Tips for a Perfect Finish
- Primer: Always use 1 coat of primer for new walls.
- Two Coats: For rich colors and durability, 2 coats are the industry standard.
- Wastage: Always buy 10% extra for touch-ups and spills.
